DOOR-FASTENING MEANS:

Specification of Letters Patent.

Patented Feb. 16, 1909.

Application tiled June 5, 1908. Serial No. 436,907.

T o all whom fit may concern.

Be it known that l, JAMEs JACKSON, a citizen of the United States, jresiding` at Hunter, in the county of Greene and btate of New York, haveinvented new and useful Improvements in Door-Fastening Means, of whichthe following is a specification.

The invention relates to an improvement in door fastening means and isparticularly directed to a manually operable device whereby the securingmeans oi' the door may be readily actuated to release the door whendesired.

The invention consists in the combination with a door, of upper andlower securing bolts therefor, a bearing block secured to the doorintermediate the bolts, a trunnion mounted in the bearing block andhaving one end projecting beyond the same, a cap plate secured to thebearing block and overlying the trunnion, that portion of the cap plateoverlying the trunnion comprising spaced strips, a handle portionprojecting at an angle to the trunnion and between the strip of the capplate and connections between the projected end of the trunnion and therespective bolts as hereinafter described and claimed.

The invention will be described in the following specification,reference being had particularly to the accompanying drawings, in which:

Figure 1 is a perspective view illustrating the application of myimprovement. Fig. 2 is an enlarged broken vertical section through thesame. Fig. 3 is a perspective of the cap plate of the lever bearing.Fig. 4 is a perspective of the base block of said bearing. Fig. 5 is aperspective of the lever.

Referring particularly to the accompanying drawings, the door 1, withwhich the invention is adapted for use, is provided with upper and lowerfastening means 2, which fastening means for the purposes of the presentinvention are shown as identical and each include a casing 3, in whichis slidably mounted a bolt 4C having a reduced stem 5 terminallyprojected through an opening in the casing, said stem within the casingbeing encircled by a thrust spring 6, adapted to bear between the boltproper and casing and to normally maintain the bolts in projected orlocking position. The upper bolt is designed to coperate with a keeper7, while the lower bolt may, if preferred, engage a recess 8 in the sillof the door. Secured between and slightly to one side of a line joiningthe respective bolt casings is a bearing includincf a base block 9 ofapproximately rcctangiilar shape and formed with openings 10, whereby itmay be secured to the door. Secured on the face of the block is abearing projection 11 which, in a line transverse the block, is formedwith a semicylindrical depression or bearing recess 12. A cap plate 13is designed to coperate with the block 9 having plate sections 14 torest snugly upon the plain portions of the block 9 above and below thebearing projection 11, and an intermediate ollset section 15 formed ofspaced strips 1G, which are arranged to overlie the bearing depression12 in the block when the parts are assembled. A lever 17 is arranged forcoperation with the bearing including a handle portion provided at oneend with a trunnion 18 disposed at an angle to the handle portion and ofa size to seat in the depression 12 in the block 9. lith the trunnion inthe bearing block the handle of the lever will project between thestrips 16 of the central portion ot the cap plate, whereby a limitedmovement of the lever and a corresponding rotation of the trunnion ispermitted. One end of the trunnion is circumferentially enlarged toprovide a barrel 19, the free end of which is headed at 20. Atdiametrically opposing points the barrel of the trunnion is providedwith eye bolts 21 from which flexible connectors, as chains 22,

extend for connection with the free terminals of the stems 5 of thelocking bolts. By this construction it is obvious that by movement ofthe lever in one direction the barrel is partially rotated with theeffect to partly wind the chains 22 thereon and thereby retract thebolts 4 from their respective keepers against the tension of the springs6. By a sin le movement of the lever, therefore, the astening means aresimultaneously released and the door permitted free movement.

The invention is particularly designed toward providing an easilycontrolled and conveniently operated releasing means for the doorfastening used in emergency exits in public halls, theaters, schools, orthe like, the operation being such as to require no particular knowledgeor skill to elect release of the door.

As a particular and salient feature of the resent invention it is to benoted that the ever when in normal position will project approximatelyat right angles to the surface of the door and that the release of thefastening means may be readily accomplished by moving said lever ineither direction. This materially simplifies the release of the doorsand thereby guards against uncertainty of operation by one notparticularly familiar with the construction.

Having thus described the invention what is claimed as new, is

1. The combination with a door, of upper and lower securing boltstherefor, a bearing block secured on the door intermediate the bolts, atrunnion mounted in the bearing block and projecting at one end beyondthe same, means for holding the trunnion in position in the bearingblock, connections intermediate the projected end of the trunnion andthe respectlve bolts, and a lever secured to the trunnion and projectingat right angles therefrom, whereby said lever is operative in a plane atright angles to the plane of the door.

2. The combination with a door, of upper land lower securing boltstherefor, a bearing block secured to the door intermediate the bolts, atrunnion mounted in the bearin block and having one end projected beyonthe same, a cap plate secured to the bearing block and overlying thetrunnion, that portion of the cap plate overlying the trunnioncomprising spaced strips, a handle portion projecting at an angle to thetrunnion and between the strips of the cap plate, and connectionsbetween the projected end of the trunnion and the respective bolts.

In testimony whereof I aiix my signature in presence of two witnesses.

JAMES JACKSON.
